Design Requirements For Drying Rooms In Car Paint Booths

Design requirements for drying rooms in car paint booths

Drying is one of the three main processes in the process of industrial car paint booth in automobile paint booth. It converts liquid film into solid film quickly, so this process is also called curing process, which is for production efficiency and coating quality. It has a direct impact on the cost of car paint booths.

Drying is achieved by dedicated heating equipment, which is called a drying room. The drying room for high decorative car paint booths should meet the requirements of cleaning, energy saving and environmental protection. The following conditions should be met.

Should meet the quality requirements of automotive paint booths. The car paint booth should be able to meet the specified temperature-time curve of the workpiece to be dried; the temperature distribution of the workpiece is even; the drying room is clean and dust-free; the decomposition of the decomposition products generated during the drying process should be avoided.

High energy efficiency. Energy recycling; the structure and thermal insulation of the import and export of the drying room, the housing and the air duct are excellent, and the heat loss is small. It should comply with the relevant regulations on the safety and fire prevention of automotive paint booths. There should be no pollution to the workshop and the atmosphere, and the discharged organic volatiles should meet the standard. Solvent-free or other odor, there should be no risk of explosion.

It should be easy to clean and repair. There is no dead angle in the drying room, the ventilation pipeline can be accessed, and it is easy to clean; the inner wall of the drying room of the car paint booth is well sealed to ensure that harmful exhaust gas does not enter the factory; In foreign countries, natural gas and oil are generally used as heat sources for drying rooms for automobile paint booths; natural gas, gas or diesel oil is used as a heat source in areas where domestic oil and gas resources are abundant; electricity is used in areas where electricity prices are cheaper. Heat transfer is the heating of the paint film by heating the object by means of a burner or an electric heater by means of radiation, convection or a combination of the two.

Radiant heating is used in the warming zone, and hot air is used for convection heating in the warming zone. Radiant heating is usually used in the heating zone of the continuous production of the topcoat and the intermediate coating drying room to ensure high dust-free and low wind speed of the effective space in the case where the coating film in the heating zone is not dry and easy to stick.

Circulating hot air convection heating is widely used in the automotive industry. This method is used in almost all car paint drying rooms. It has the advantage of uniformly heating the dried objects with complex geometry and structure to ensure the temperature distribution of the dried materials. Very uniform.
